The game of musical chairs could involve CUSA and the Sun Belt if Colorado State is invited to the P5 party.
In a previous piece regarding the potential impact of Big XII EXPANDAPALOOZA, I conjectured that Colorado State moving to the Big 12 could result in a major change to Conference USA.
Let's run with that for a second. There's a bit of logic to such a move; the Mountain West Conference would drop to 11 programs and would likely attempt to poach another program to get back to an even 12.
While my personal opinion would be to add soon-to-be independent New Mexico State in order to make the transition less of a hassle, I do not see that happening.
